The subfamily Scaphirhynchinae is comprised of six The sturgeon subfamily Scaphirhynchinae contains two genera species, three in Scaphirhynchus from North America, and of obligate freshwater sturgeon: Scaphirhynchus and Pseudo- three in Pseudoscaphirhynchus from Central Asia (Nelson, scaphirhynchus, from North America and Central Asia, 1994; Mayden and Kuhajda, 1996).

A novel data set containing multiple individuals with members of Acipenserinae exhibiting variable life history representing four diagnosable morphological variants for two strategies (i.e. anadromous, amphidromous, and potamodr- species of Pseudoscaphirhynchus, P. hermanni and P. kaufman- omous; Bemis and Kynard, 1997), while members of Scaph- ni, was generated. These data were used to test taxonomic irhynchinae complete all aspects of their life history as obligate hypotheses of monophyly for the subfamily Scaphirhynchinae, freshwater river inhabitants (potamodromous; Bemis and monophyly of both Scaphirhynchus and Pseudoscaphirhynchus, Kynard, 1997).

Licensed under CC BY-NC 3.0. Available: http://eol.org/data_objects/20923584. (June 2018). 1 Native Range and Status in the United States Native Range From Qiwei (2010): “The species was known from the Caspian, Black and Aegean Seas. It is now extirpated from the Aegean Sea, and in the Black Sea basin the last natural population migrates up the Danube where it is heavily overfished. Only very few spawners remain in the rest of the Black Sea basin.” Status in the United States This species has not been reported as introduced or established in the United States. Means of Introductions in the United States This species has not been reported as introduced or established in the United States. 1 Remarks From Qiwei (2010): “Red List Category & Criteria: Critically Endangered […]” “Based on catch data, and number of individuals migrating into the Volga and Ural rivers it is estimated that the species has undergone a population decline of at least 80% (possibly close to 100%) in the past three generations (minimum estimate of 30 years, possibly up to 40), which is expected to continue. Catch data shows massive declines across the species range with a 98% decline between 1980 and 2007 in the Caspian Sea, and a 72.5% in four years (2002-2005) in Romania (Danube).” “In the early 1990s it was estimated that nearly 100% of the Sea of Azov population and 30% of the Caspian Sea population were from stocking.

Available: http://eol.org/data_objects/2005171. 1 Native Range and Status in the United States Native Range From Gesner et al. (2010): “This species is known from rivers draining to Black, Azov and Caspian Seas; Siberia from Ob eastward to Yenisei drainages. Its current strong holds are the Volga, Ural and Danube systems.” From CITES (2000): “It originally inhabited the rivers of Eurasia, being widely distributed in rivers flowing into the Caspian, Black, Baltic, White, Barents and Kara Seas and the Sea of Azov.” Status in the United States No reliable records of Acipenser ruthenus in the United States were found. A record of Acipenser ruthenus for a location near Baltimore, Maryland was found (GBIF 2013). No other records indicate any Acipenser ruthenus within the United States. The record dates 1 from 1888 and cannot be determined if it is the result of a voucher specimen with the Smithsonian Institution or a misidentification. Means of Introductions in the United States No records of Acipenser ruthenus in the United States were found. Remarks Witkowski and Grabowska (2012) and CITIES (2000) state that Acipenser ruthenus may be able to hybridize with other Acipenser species and with Mississippi Paddlefish Polyodon spathula. 2 Biology and Ecology Taxonomic Hierarchy and Taxonomic Standing From Eschmeyer et al. (2017): “ruthenus, Acipenser Linnaeus [C.] 1758:237 [Systema Naturae, Ed. X v. 1] ?Danube River. Holotype: NRM 96. Based on several sources, see Kottelat 1997:31 so 96 should be regarded as a syntype.

  • Sturgeon Hatchery Manual
    FAO ISSN 2070-7010 FISHERIES AND 558 AQUACULTURE TECHNICAL PAPER 558 STURGEON HATCHERY MANUAL This Sturgeon Hatchery Manual includes the latest available scientific research findings and experiences and compiles advice given in earlier manuals and handbooks on sturgeon culture and reproduction practices. This document was prepared in response HATC STURGEON to numerous requests for practical guidance on this subject from the Central Asian and Caucasus region to the Food and Agriculture Organization of the United Nations (FAO). This manual is targeted particularly at sturgeon farmers, sturgeon hatchery operators, hatchery technicians, and fisheries and aquaculture managers involved in sturgeon aquaculture development and the restocking and rehabilitation of sturgeon populations in the countries around the basins of the Black and Caspian seas. It aims to provide a practical handbook of modern sturgeon hatchery practices and management. The H manual is available in the English, Russian and Turkish languages.
